Example (b):

as shown in figures 1 to 4:

the utility model provides a double-layer banana screen based on fluorite mineral product processing, which comprises a lower support frame 1; the top of the lower support frame 1 is fixedly and symmetrically connected with four support columns 2 in total through welding; the top parts of the four support columns 2 are all fixedly provided with a high-strength spring 3; a sieve box 5 is arranged above the lower support frame 1, and four connecting seats 4 are fixedly arranged on the left side and the right side of the sieve box 5; the bottoms of the four connecting seats 4 are respectively fixedly connected with the tops of the four high-strength springs 3; the bottom of the screen box 5 is fixedly connected with a material collecting groove 10;

the left side and the right side of the screen box 5 are both fixedly provided with a vibrator 6; an upper sieve plate 8 and a lower sieve plate 9 are fixedly arranged in the sieve box 5; the diameter of the round holes on the upper sieve plate 8 is 40mm, so that fluorite particles smaller than 40mm can pass through the round holes on the upper sieve plate 8 and fall to the top of the lower sieve plate 9, and grading screening is facilitated; a feed hopper 7 is fixedly arranged at the top of the rear side of the screen box 5; the front half of the inclined plate at the rear side of the feed hopper 7 is positioned above the opening between the bottom end of the front inclined plate and the inner wall at the rear side of the screen box 5, so that the feed hopper 7 can block and buffer all falling fluorite.

Wherein, the top of going up sieve plate 8 is fixed to be provided with four wedge column archs, and the wedge column arch at 8 tops of upper sieve plate in the rolling in-process of fluorite granule can play and block the effect of slowing down, disperses more when also enabling the fluorite granule to roll down moreover, and the screening also will be more thorough like this.

Wherein, the front and back side of feeder hopper 7 is an hang plate, and the distance of the hang plate bottom of front side and 5 rear side inner walls of sieve case is 60mm, the majority can fall on the hang plate top of feeder hopper 7 front side when fluorite falls down, some can fall on the hang plate top of rear side in addition, then these fluorites can fall down and fall on 8 tops of last sieve plates through the opening between the hang plate bottom of front side and the 5 rear side inner walls of sieve case along the hang plate, consequently just can not directly cause the striking to last sieve plate 8, avoid going up sieve plate 8 and warp because of the striking.

Wherein, the diameter of the round hole on the lower sieve board 9 is 12mm, the fluorite granule that falls through the round hole on the last sieve board 8 will be screened through the round hole on the sieve board 9 down, sieve 9 top can only remain the fluorite granule of 12mm-40mm granularity and roll out to the front side down at last, and the fluorite granule that is less than 12mm then can fall in the collection silo 10 of sieve 9 bottom down and fall out downwards through the opening of collection silo 10 bottoms, the fluorite granule of big granule then can be separated and roll out at last sieve 8 top and to the front side, and then accomplish the classified screening.

The specific use mode and function of the embodiment are as follows:

in the utility model, the lower support frame 1 is fixed on the ground before use, when the device is used for screening fluorite particles, two vibrators 6 are firstly opened, at the moment, the screen box 5 can continuously vibrate under the support of the high-strength spring 3 at the top of the support column 2 through the connecting seat 4, the upper screen plate 8 and the lower screen plate 9 inside the screen box can synchronously vibrate, at the moment, fluorite in superior equipment can be poured into the feed hopper 7, most of the fluorite can fall on the top of the inclined plate at the front side of the feed hopper 7 when falling down, and one part of the fluorite can fall on the top of the inclined plate at the rear side, then the fluorite can slide down along the inclined plate and fall on the top of the upper screen plate 8 through the opening between the bottom of the inclined plate at the front side and the inner wall at the rear side of the screen box 5, therefore, the impact on the upper screen plate 8 can not be directly caused, the deformation of the upper screen plate 8 due to the impact can be avoided, and the front half part of the inclined plate at the rear side of the feed hopper 7 is positioned above the opening between the bottom of the front inclined plate at the rear side of the front inclined plate at the front side and the inner wall at the rear side of the screen box 5, so the feed hopper 7 can stop and buffer all falling fluorite, the fluorite particles can continuously roll downwards by matching with vibration after falling to the top of the upper sieve plate 8, the wedge-shaped columnar bulge at the top of the upper sieve plate 8 can play a role of stopping and decelerating the fluorite particles in the rolling process, and the fluorite particles can be more dispersed when rolling downwards, thus the screening can be more thorough, then the fluorite particles smaller than 40mm can pass through the round hole on the upper sieve plate 8 and fall to the top of the lower sieve plate 9, the fluorite particles falling through the round hole on the upper sieve plate 8 can pass through the round hole on the lower sieve plate 9 for screening, finally, only the fluorite particles with the granularity of 12mm-40mm can be reserved at the top of the lower sieve plate 9 and roll out to the front side, and the fluorite particles smaller than 12mm can fall into the material collecting groove 10 at the bottom of the lower sieve plate 9 and fall out downwards through the opening at the bottom of the material collecting groove 10, the large-sized fluorite particles are separated from the top of the upper sieve plate 8 and rolled out to the front side, and then the classified screening is completed.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
